なお、靴の中敷き1がEVA素材からなる場合には、TPUにより成型された硬質カップ10は130トン〜150トンの圧力で靴の中敷き1に圧着される。 Incidentally, insole 1 shoes when made of EVA material, rigid cup 10 which is molded by TPU is crimped to insole 1 shoe at a pressure of 130 t to 150 tons.

図3は、図1に示された靴の中敷き1の裏面における構成を示す平面図である。 Figure 3 is a plan view showing the construction of the shoe back surface of the insole 1 shown in FIG. 図3に示されるように、靴の中敷き1の裏面には、靴を履いた際における足の親指の付け根相当部分から小指の付け根相当部分まで足の各指の付け根相当部分を結んでできる曲線に沿って凸設された線状凸部8が靴の中敷き1の一部として一体的に形成される。 As shown in FIG. 3, the curve can be on the back side of the insole 1 shoe, by connecting the base corresponding portions of each finger foot from the base corresponding portion of the toe at the time of wearing shoes to base a substantial portion of the little finger the line-shaped protruding portion 8 which is protrudingly provided is integrally formed as part of the insole 1 shoes along.

なお、図3においては、一例として中央部分で切れ目を有する三本の線状凸部8が示されるが、線状凸部8の本数や切れ目の数、あるいは線の間隔は種々のものが考えられ、切れ目はなくても良い。 In FIG. 3, but three of the line-shaped protruding portion 8 having a cut in the central part as one example is shown, the number of number and breaks the line-shaped protruding portion 8 or the line spacing, the idea are various it is, may not be cut.

そして、このような靴の中敷き1の裏面に形成される線状凸部8に沿って中敷き1を切断すると、中敷き1は長さ方向に爪先部分を欠いた形状となる。 When cutting the insole 1 along the line-shaped protruding portion 8 formed on the back surface of the insole 1 in such shoes, insoles 1 has a shape lacking the toe portion in the length direction. これにより、中敷き1は装着する靴が先端を細くしたデザインの場合などにも使用することができる。 Thus, the insole 1 can also be used in a case of design shoe mounting has narrowed tip.

また、靴の中敷き1の裏面には上記のように、足の各指の付け根相当部分から踵相当部分までを覆うように装着される硬質カップ10が装着される。 Further, on the back surface of the insole 1 shoe as described above, a rigid cup 10 that is attached to cover from the base a substantial portion of each finger of the foot to the heel corresponding portion is mounted.

ここで、硬質カップ10は、図3に示されるように、足の外側(側面1b側)よりも内側(側面1a側)の長さが長くなるように形成される。 Here, the hard cup 10, as shown in FIG. 3, the length of the inner (side 1a side) is formed to be longer than the outer legs (side surface 1b side).

また、硬質カップ10には、足の親指の付け根相当部分から踵相当部分の間において設けられ、靴の中敷き1を構成する材料で靴の中敷き1と一体的に充填される第1の空隙部と、小指の付け根相当部分から踵相当部分の間において設けられ、上記材料で靴の中敷き1と一体的に充填され上記第1の空隙部より面積の小さい第2の空隙部とが形成される。 Further, the rigid cup 10 is provided between the base corresponding portions of the toe of the heel corresponding portions, a first gap portion is filled shoe insole 1 and integrally with the material constituting the insole 1 shoes When provided between the base corresponding portion of the little finger of the heel corresponding portions, and a small second void portion area than insoles 1 is integrally filled in the first gap portion of the shoe in the material is formed .

このような構成によれば、足の内側面及び外側面に柔軟性を持たせつつ両側面のサポート力を高めることができる。 According to such a configuration, while flexibility on the inner and outer surfaces of the legs can be enhanced support force of both sides. さらに、硬質カップ10による足裏のサポートを維持しながら側面による足への圧迫を少なくすることができ、硬質カップ10による足骨格の支持及び足のスムーズな動きを維持することができる。 Furthermore, it is possible to reduce the pressure on the foot by side while maintaining the support sole according to rigid cup 10, it is possible to maintain a smooth movement of the support and the foot of the foot skeleton by rigid cup 10.

ここで、上記第1及び第2の空隙部は、孔あるいはスリット形状が考えられる。 Here, the first and second gap portions are conceivable hole or slit shape. 例えば、形状が一定の大きさの孔の場合、第1の空隙部は複数の孔からなり、第2の空隙部は上記孔の数より少ない数の孔からなる実施形態が考えられる。 For example, if the shape of a certain pore size, the first gap portion comprises a plurality of holes, the second gap portion embodiment having the smaller number of holes than the number of the holes are contemplated. そして、図3においては一例として、第1の空隙部は4つの衝撃拡散孔6から構成され、第2の空隙部は3つの衝撃拡散孔6から構成される。 Then, as an example in FIG. 3, the first gap portion is composed of four impact diffusion holes 6, second void portion consists of three shock diffusion holes 6.

また、硬質カップ10には、足の踵部に形成され靴の中敷き1を構成する材料で靴の中敷き1と一体的に充填された踵孔部7が設けられる。 Further, the rigid cup 10 is Kakatoana part 7 which is integrally filled insole 1 and the shoes material constituting the insole 1 shoe is formed in the heel portion of the foot are provided.

硬質カップ10に上記のような衝撃拡散孔6や踵孔部7が設けられることにより、硬質カップ10に柔軟性が生じるため、着地時に受ける衝撃を適度に分散させることができ、同時に足裏の安定性を保つことができる。 By impact diffusion holes 6 and Kakatoana unit 7 as described above in the hard cup 10 is provided, the flexibility to rigid cup 10 occurs, it is possible to appropriately disperse the impact received at the time of landing, at the same time the sole of it is possible to maintain the stability.

さらに、硬質カップ10は、親指又は小指の付け根相当部分から踵相当部分へ延伸し、上記第1又は第2の空隙部の中央側で隣接するよう配置され、硬質カップ10を構成する材料により硬質カップ10と一体的に靴と接する側に凸設されるバランサー11を有する。 Furthermore, the hard cup 10 extends from the base corresponding portion of the thumb or the little finger to the heel corresponding portions are arranged adjacent to each other in the center side of the first or the second void part, hard the material constituting the rigid cup 10 cup 10 integrally with the balancer 11 to be projectingly provided on the side in contact with the shoe.

そして、かかるバランサー11により、硬質カップ10の強度が高められると共に適度な弾力性が実現されるため、着地等の衝撃により変形した硬質カップ10にバネのような機能を発揮させることによって、足が地面を蹴り出す力を生むことができる。 By such balancer 11, for appropriate elasticity along with the strength of the rigid cup 10 is increased is achieved by exerting a function as a spring hard cup 10 which is deformed by an impact of landing, etc., feet it is possible to produce a force to kick the ground.

図4は、図1に示された靴の中敷き1を側面から見たときの構成を示す側面図である。 Figure 4 is a side view showing the structure when viewing the insole 1 shoe shown in Figure 1 from the side. 図4に示されるように、靴の中敷き1の裏面には上記のように一体的に足幅方向に形成され切断線とし得る線状凸部8が設けられる。 As shown in FIG. 4, the line-shaped protruding portions 8, which may be a formed in the integrally foot widthwise cutting line as described above is provided on the back surface of the insole 1 shoe.

また、底面に装着された硬質カップ10は足の土踏まずの部分12が反り上がるように形成され、かかる部分12に上記のような凸状のバランサー11が設けられる。 Also, rigid cup 10 attached to the bottom surface is formed to rise warp portion 12 of the arch of the foot, convex balancer 11 as described above can be provided in such parts 12.

このように、土踏まずの部分を反らせて足裏の形状にフィットさせ、靴の中に隙間を生じさせないことによって、足がぶれにくくなり安定するので、快適な歩行や走行を実現することができる。 In this way, by deflecting a portion of the arch to fit the foot of shape, by not causing a gap in the shoe, so that stability is difficult legs shake, it is possible to realize a comfortable walking or running.

以上より、本発明の実施の形態に係る靴の中敷き1によれば、足の接触面において、足の親指の付け根相当部分と小指の付け根相当部分の間になだらかに隆起する中央凸部2が形成されることにより、図5の曲線AR1で示される足幅方向の骨格の並びを好ましい位置に配置させることができるため、親指側の曲線AR2及び小指側の曲線AR3に沿った方向においても足の骨の隙間がバランスよく配列され、結果として靴を履いた際の足全体の骨格を適正に整える(組む)ことができる。 From the above, according to the insole 1 the shoe according to an embodiment of the present invention, the contact surface of the foot, the central convex portion 2 to gently bulge between the root corresponding parts and root substantial portion of the little finger of toe by being formed, it is possible to arrange the preferred position the arrangement of the foot width direction of the skeleton represented by the curve AR1 in FIG. 5, the foot also in the direction along the thumb side of the curve AR2 and the little finger side of the curve AR3 gap of the bone is well-balanced array, the result as the backbone of the entire foot when wearing the shoes properly adjust (partnering) can be.

このことにより、靴を履いた際における足の筋肉の働きが正常化され、足の本来の機能である安定性や衝撃吸収性、蹴り出す力を発揮させることができ、その結果として前後左右の動きのコントロール性が高められるため、足の負担を従来よりも一層軽減することができる。 Thus, the normalization functions of leg muscles in the time of shoes, original function is that stability and shock absorption for the foot, it is possible to exert a force kick, front, rear, left and right as a result since the control of the motion is increased, it can be further reduced than the conventional foot burden.

また、上記足の接触面において、中央凸部2の両側で親指の付け根相当部分又は小指の付け根相当部分から踵相当部分に延伸する中央凹部3が形成されるため、足の親指及び小指の付け根から踵に向かう足裏の腱のスムーズな動きも実現することができ、かかる点でも足への負担を軽減することができる。 Further, the contact surface of the foot, because the central recess 3 which extends from the base corresponding portions of the base corresponding portion or the little finger of the thumb on both sides of the central convex portion 2 in the heel corresponding portion is formed, the base of the big toe and pinky from the smooth movement of the sole of the tendon toward the heel can also be realized, it is also possible to reduce the burden on the feet at this point.

また、中敷き1を装着する靴のデザインにより中敷き1全体が挿入できない先細の靴、あるいはサイズの小さい靴などの場合、中敷き1の裏面の線状凸部8から切断して使用することができる。 Also, shoes tapered entire insole 1 by a design of the shoe mounting insole 1 can not be inserted or in the case of such small shoe sizes, it can be used by cutting from the back surface of the line-shaped protruding portion 8 of the insole 1. この切断した中敷きは各指の付け根部分から踵部を支持するので、足への負担軽減効果を満足できる。 Since this cut insoles to support the heel portion from the base portion of each finger, it can satisfy the burden effect on the foot.

また、硬質カップ10において上記のように足の外側及び内側に空隙部を形成することによって、足の両側面における柔軟性を担保して足への圧迫を少なくすると共に、硬質カップ10による足の裏部および両側での支持力を維持することができるため、靴の中敷き1の装着感を改善しつつ硬質カップ10による上記及び以下の効果を得ることができる。 Further, by forming the gap portion in the outer and inner legs, as described above in the hard cup 10, as well as reducing the pressure on the foot and ensure flexibility in both sides of the foot, the foot by a rigid cup 10 it is possible to maintain the supporting force at the back part and on both sides, it is possible to obtain the above and the following effects of rigid cup 10 while improving the fit of the insole 1 shoe.

硬質カップ10は、上記のように靴の中敷き1の材料に比して強度の大きな熱可塑性ポリウレタン(TPU)等で成型されているため、図5に示された第5中足骨B1の後部にある突起を点ではなく面で支えることによってかかる突起への負荷を分散し、足の内側の曲線AR2に沿った骨格だけでなく外側の曲線AR3に沿った骨格も柔軟にしっかりと支持することができる。 Hard cup 10, because they are molded with a large thermoplastic polyurethane (TPU) such as strength compared to the material of the insole 1 shoe as described above, the rear portion of the fifth metatarsal B1 shown in FIG. 5 there distribute the load to such projections by supporting a plane rather than a protrusion at the point, skeleton along the outside of the curve AR3 well backbone along the inside of the curve AR2 foot be flexibly firmly supported can. これより、人の体の左右方向のスムーズな体軸移動が実現される。 From this, a smooth body axis movement in the lateral direction of the human body is achieved.

また、硬質カップ10は、図5に示された踵骨B2にある突起を踵孔部7等で支持することにより、踵のぐらつきを抑え、曲線AR1,AR2,AR3に沿った骨格を最適に整える(組む)ことができるため、靴を履いた足を安定させることができ、着地時に生じ得る足のぶれもなくすことができる。 Further, the hard cup 10, a protrusion on the heel bone B2 shown in FIG. 5 by supporting at Kakatoana unit 7 and the like to suppress the wobble of the heel, the curve AR1, AR2, optimally the skeleton along the AR3 because that can adjust (partnering) that, it is possible to stabilize the foot wearing the shoes, shake of the foot, which may occur at the time of landing can be eliminated.

1 靴の中敷き、2 中央凸部、3 中央凹部、6 衝撃拡散孔、8 線状凸部。 1 shoe insoles, 2 central protrusion, 3 central recess, 6 impact diffusion holes 8 linear protrusions.
